Appneatien ala March 12, 1910. serial No. 548,810.

To all whom *it may concern.:

. Be it known that I, J osnrn W. ROGERS, a citizen of the'United States,residing at Woodbury,v in the county of Gloucester, State of New Jersey,have invented an Au` tomatic Signaling Mechanism, of which the followingis a specification.

This invention is an automatic signaling mechanism designed primarilyfor .railway crossings, particularly for use 'withtrains operating inboth directions on a track.` 'I

The apparatus comprises t-wo starting relays located respectively oriopposite sides of the crossing and a signal relay located atthecrossing.

vThe desired result eii'ected by my invention is the automatic operationof a signal by a train as it approaches the crossing from eitherdirection and the automatic discontinuance of the signaling operationafter the train has reached a desired point or after the lapse of adesired period.

The characteristic construction and functions of the invention are fullydis-closed in the. following description and the accompanying. drawingsin illustration thereof.

' Contact point d, the conductor o containing- 'In the drawings, Figure.1. is a diagram matic representation of my lmprovements;

-' and Fig.,-2 is a-diagrammatic representation of. a modifiedconstruct-ion for cutting out the signal.

The invention-as illustrated in Fig. 1 is applied to a track comprisingthe conductlng sectionswA, -A and A2 insulated by non-V conductingsections A5, A", A5 and A".

A rail of the section- A is divided by insulation a intosections a2 anda and a rail of the section A2 is' divided by insulation a* v intosections a. and fof. vThe section A is provided with-a starting relaycomprising a battery B connected by a conductor b wlth the rail a7, andby the conductor-c with a the electro-magnet e. A conductor-7c connectsthe conductor c with the rail section aa and contains th'eelectro-magnet g. A conductor is tapped onto the 'conductor f and isprovided with the contact point z'. A conductor j connects therailsection a2 with an armature lc adapted to oscillate between thecontacts l and t, means such as a spring m serving to hold the armature7c in engagement with .the contact Z normally. On the opposite side ofthe crossing is the second starting relay comprising the battery B, the

conductor b connecting it with therail section a8 and thel conductor-oconnecting it with the contact lpoint d', .the conductor c containingthe electro-magnet e. A 'conductor f connects the Wire c .with the railsection a and contains the electro-magnet g. A conductorl h connects theconductor f with .the'contac't point z". A conductor j" connects therail section a with an armature la which is adapted to oscillate betweenthe` contacts cl and means such as a coiled spring m being provided tohold this armature in engagement with the contacty d nor mally. i

The electro-magnet is adapted for attracting an armature n to effectits'engagement wlth the contact point o, the armature being-heldnormally out of engagementwith the electro-magnet'and contact point by isuitable means as a spring p. A conductor g-connects the armature n witha conductor R and a conductor s connects the contact point o .with aconductor T.

The electro-magnet e is' adapted for lattracting the armature 'n' andeffecting its engagement with the-contact point 0,', the armature beingheld normally out of engagement with the electro-magnet and con# tactpointby the spring 79.. The armature 1s. connected by the conductor g"with the conductor R and the contact point oAis connected by theconductor-s with the con- I ductor T.

The crossin 4relay comprises the battery v the conductor b2 withthe B2vconnected conductor Tand by the conductor o2 with the conductor R, theconductor c2 containlng the electro-magnet e2. A conductor d 4connectsthe conductor b2 througha coiled spring da with an armature f2 adaptedto be attracted by the electro-magnet 'e2 against the action of a,spring da which normally withdraws it from the electro-magnet.

A contact point g? is connected through the resistance coil h2 with theconductor c2 on one side of the electro-magnet e2 and a con- `tact.point '2 is' connected through the bell J with the conductor o2 on theother side of this electro-magnet, these contact points being engaged bythe armature f2 when the latter is .attracted `by the electro-magnet e2.The resistance is used to prevent short circuiting the'ba'ttery and toreduce the potential across the terminals of the magnet correspondingthereto. Conductors u and u' connect Athe terminals of theelectro-magnet e2 with the respective rails a and a ot the section A.

In operation, with a train direction of the arrow, when it reaches thetrack section A a circuit of the battery B is completed through thewheels v and the axle Q1 connecting the rail sections a2 and a7,

upon which current flows through the con-` ductors b, al, c, "v, o, a2,y', 7c, and c, exciting the electro-magnet e and drawing the armature/nlinto engagement with the contact 0. This completes a circuit of thebattery B2 and current flows, therefrom through its conductors b2, T, s,n, g, R and c2, exciting the electro-magnet e2. This electro-magnet nowdraws the armature f2 into engagement with thel contacts g2 and 2.Current now Hows through the resistance and signal circuits, from thebattery B2through the conductors b2, (Z2, and f2 to the contacts g2 and2, the current diyiding here so that part of it returns to the batteryby way of the resistance coil h2 and the electro-magnet e2 and theremainder by way of the circuit of the signal J, the latter beingsounded.

When the train has passed the insulation a, the circuit containing theelectro-magnet c is broken and the armature n is released, breaking thecircuit of the battery E2 con'- taining this armature. In this positionof the train, the circuit containing the electro-- magnet g is closedand the armature if: is

- withdrawn from the contact point cl, without however effecting theoperation of the signal.' T he' bell continues to ring until the trainreaches the track section A when the signal is discontinued by theconnection of the conductors uand u through the wheels 1f and axle c.lCurrent now flows from the battery B2 through the conductors b2, (Z2,f2, u, 0, Q1', '0, u and c, cutting'out the electro-magnet e2 andpermitting the spring d3 to .withdraw the armature f2, which breaks thebell circuit. The train passes the second starting relay withoutringingthe bell because when the rails of"v and as areconnected currentHows from the battery B through the conductors b', as, u', fu', 1), a5,f and c, exciting the electro-magnet gvwhich attracts the armature lc.This withdraws the arma- 'ture from the contact d, consequently thecircuit containing the electro-magnet e is broken and the armature nremains in its moving in the The mechanism shown in Fig. 2 representsamodiiied construction orcutting out the signal after the lapse of apredetermined period of time. In this construction a conductor c4connected with the contact 'i2 is wound upon a metal coreA w containedin a box w of the same material, the box having a contact lw2 connectedby the conductor 03 with the conductor 02 and electrically separated by.insulation w3 from the conyducting material of the box. A conductor c5connectsthe box fw with the conductor c2 so as to cut out theelectro-magnet e2. When,

as previously described, current flows backl y to the battery throughthe conductor c2, exciting the electro-magnet ve2 and drawing thearmature f2 into engagement with the contacts g2 and i2, the signal J issounded by current lowing'throughthe conductors b2, di', f2, and 2 backto the battery by way of `the bell circuit. At4 the same time currentflows vthrough the conductor c4 through the coil around the core w,heating and expandving the latter so that it is brought into engagementwith the conductor cu2. Current now flows by way of the conductors c5,w', w, 102,03, and c2 to the battery, cutting out the electro-magnet eand releasing the armature f2, broken.
